Google rolls out March 2026 Core Update
Google is expanding its multimodal Search Live experience to all regions where AI Mode is available, including Germany, as part of a broader Search product push tied to its March 2026 Core Update. Search Live lets users interact with Google’s AI by voice and camera, returning audio responses and transcripts. The feature will be powered by the new Gemini 3.1 Flash Live model — distinct from Gemini 3.1 Flash‑Lite — which promises faster, more natural dialog, doubled conversation memory for Live sessions, and multilingual support. Gemini 3.1 Flash Live will appear across Search Live, Gemini Live in the Gemini app, via the Gemini Live API in AI Studio, and in Google Cloud for enterprises. The rollout covers over 200 countries and regions. The article also notes Google’s introduction of a Google‑Agent user agent aimed at AI agents that browse the web, a development highlighted by Semrush.
Google Completes March 2026 Core Search Update
Google has finished rolling out its March 2026 Core Update after roughly twelve days, with the rollout declared complete on April 8, 2026. The update follows a short March 2026 Spam Update and arrived amid elevated search volatility. Early analyses show first ranking shifts across verticals and countries: some pages (including certain UGC and original content) report gains while others have dropped. Semrush flagged high desktop volatility in Germany (9.4/10). Google advises site owners to continuously optimize content and site quality and published guidance for large updates; it also exposed new fetcher tooling (a "Google-Agent" user agent) and references AI-related search features such as AI Overviews. Early Semrush data suggests human-written blog content is outperforming some AI-generated content at top positions.

It will have its own Workspace account with an email address, and will write its own audit trail. Early testers include On, Shopify, and PayPal. Gemini has over 1 billion monthly active users, and nearly 90% of Fortune 100 companies use Gemini Enterprise.
